The map for the Energy Centre is already finished! It's smaller than all of the main areas, but bigger than Awakening. Like Awakening, rather than having a mix of hardcoded and random encounters, there will only be a few encounters and all of them will be hardcoded. At the moment I'm looking at having two "boss" demons, something like the extra hard encounters I put at the end of each main area or the Inner Demon from Awakening.

The Energy Centre will be completely optional -- only accessible as solo Emerald and only by solving a difficult puzzle. It will be balanced around level 75.
